The prototype of the ContiMix II is located at SMC, a Eurovia subsidiary in Normandy. A simple, precise and direct method of feeding all the materials into the mixer achieves a 20% increase in output for the entire plant. Low height dimensions make it easy to conceal a continuous production plant in housing. This prevents dust, noise and odours from entering the outside environment. But that is not the only feature that makes the SMC plant particularly environmentally friendly. A new burner saves energy, whilst the rate of adding reclaimed asphalt has been raised to 40%. The desired quality and homogeneity produced with a particular recipe is maintained from the first to the last tonne of asphalt to leave the mixing plant.

Versatile asphalt mixing plant
The companies Colas and SCREG (both subsidiaries of the Bouygues Group) have operated a continuous asphalt mixing plant from Ammann in the harbour of Strasbourg since the beginning of June. The ContiMix offers cold asphalt with added emulsion, foamed bitumen technology (up to 120 °C), 40% warm reclaimed asphalt feed rates, and hot reclaimed asphalt feed rates of up to 70% via parallel drum. The environmentally friendly and resource-conserving plant has a production output of 300 tonnes per hour and is equipped with accessories that allow the use of fibres as well as the production of coloured surface coatings.

Of course, ContiMix mixing plants are not only in demand in France. They are now producing asphalt in countries such as New Zealand, Australia and Great Britain.
